Devil City, also known as Urho Wind City, is known to the local Mongolian people as "Sulumuhaq." The Uyghurs call it "Shayitan Keerxi," meaning "Devil City." In fact, this area is a typical area of Yardang landforms. "Yardang" means "steep-sided hillock" in Uyghur. Yardang landforms are best known for the Yardang area near Lop Nur in the Tarim Basin of Xinjiang. Yardang landforms are a type of wind-eroded landform formed under drought and strong winds. Located in the Urho mining area on the northwest edge of the Junggar Basin in Xinjiang Uyghur Autonomous Region, in the lower reaches of the Jiamu River, 100 kilometers southwest of Karamay City, there is a unique wind-eroded landform with an unusual shape. In Mongolian, Urho means "trap," meaning "place with a trap."
